Summer is coming so that means it is time for the Water Blob! So what is a “water blob” and how do you make one? Simple. A water blob is a large piece of plastic sheeting (a clear thin tarp) that is folded in half with the three open sides taped shut and then filled with water. See the full tutorial here. When it is done it makes a cool dry play surface. It’s the perfect activity for hot summer days for all ages, especially the toddler years!
